RH Collin Balester (6-5, 200, 26) — Lanky pitcher has 185 career big-league innings after stints with the Nationals and Tigers. The No. 2 prospect in the Washington farm system eight seasons ago, he will be shifting from the bullpen to the starting rotation.
RH Justin Grimm (6-4, 198, 24) — In the running for the fifth spot in Texas’ rotation but lost out to Nick Tepesch. Since college, Grimm has added a changeup and a slider to go with his fastball and curveball. Solid in Double-A (9-3, 1.72 ERA) last season, he was 2-3 with a 4.59 ERA for Round Rock.
RH Josh Lindblom (6-4, 240, 25) —Former Purdue standout will transition to a starter’s role after pitching more than 100 innings with the Dodgers and Phillies over the past two seasons. A part of the Michael Young trade, Lindblom will be the fifth starter for the Express.
LH Brad Mills (6-0,185, 28) — Claimed off waivers from the Angels on March 24 before the Rangers assigned him to Round Rock. Mills was a PCL All-Star with Las Vegas in 2011, when he finished with an 11-9 record and 4.00 ERA. He’ll be the No. 2 starter for the Express, behind Grimm.
RH Nick Tepesch (6-4, 225, 24)— May be in Round Rock only on Opening Day. He’ll be the Rangers’ fifth starter after going 6-3 with a 4.28 ERA for Double-A Frisco last year. As a tune-up before his first Rangers start, he’ll pitch Thursday night at Dell Diamond.
RH Randy Wells (6-5, 230, 30) — A former catcher who also was in the running for the fifth spot in the Rangers’ rotation, Wells’ progress has been slowed by elbow surgery last summer. He should be a dependable starter for the Express after making 82 starts for the Chicago Cubs from 2009-11.
LH Jeff Beliveau (6-1, 197, 26) — The Chicago Cubs’ minor-league pitcher of the year in 2011, Beliveau struggled against right-handed batters last year in his first big league season. He posted a 4.58 ERA in 22 games, and the Rangers picked him up on waivers.
LH Richard Bleier (6-3, 195, 25) —Entering his sixth season in the Rangers’ system, but his first in Triple-A. A starter until last season, when an elbow injury limited him to 32 innings over 22 games with a 3.94 ERA.
RH Lisalverto Bonilla (6-2, 164, 23) — The prized acquisition in the Michael Young trade, Bonilla is a talented prospect whose fastball has been clocked at 95 mph. He began his career as a closer, but was moved to the bullpen last season, when a thumb injury limited him to 21 Double-A appearances with a 1.64 ERA and 46 strikeouts.
RH Cory Burns (6-2, 180, 25) — Acquired from San Diego after making his major-league debut last season, when he was 0-1 with 18 strikeouts and a 5.50 ERA in 18 innings. His unusual delivery helped him record 35 saves in Double-A in 2011, and he posted a 3.18 ERA in 66 Triple-A innings last season. A member of the Rangers’ 40-man roster, he could be Round Rock’s closer.
LH Neal Cotts (6-1, 200, 33) — Won a World Series ring with the White Sox in 2005, but most recently he’s piled up strikeouts for the Express. He had a 4.55 ERA in 31.2 innings for Round Rock in 2012 — striking out 41 — but had a 7.11 ERA this spring in six innings with the Rangers.
RH Evan Meek (6-0, 225, 29) — The lone All-Star representative for the Pittsburgh Pirates in 2010, Meek has been plagued by shoulder soreness for the past two seasons. While he struggled in 12 innings for the Pirates in 2012, he posted a 2.74 ERA over 46 innings in Triple-A.
LH Nate Robertson (6-2,225, 35) — Posted a 2.19 ERA in 12.1 innings this spring after changing his throwing motion in the offseason. If his numbers remain solid, he could be called up to the Rangers bullpen.
RH Yoshinori Tateyama (5-10, 165, 37) — One of the oldest players in the Pacific Coast League, Tateyama struggled with his control last season, but he did have a brief stint with the Rangers after recording six saves for the Express.
RH Johan Yan (6-4, 185, 25) —The side-armed pitcher struggled against left-handers in 2012, but his effective sinker (clocked at about 90 mph) makes him a pain for right-handed batters. He made 28 appearances for the Express in 2012, compiling a 5.03 ERA with 24 strikeout after being promoted from Double-A.
C Juan Apodaca (5-11, 180, 26) —Made his Triple-A debut in 2005 with Las Vegas when he was 18, but didn’treturn to that level until 2012. Apodaca has a career .989 fielding percentage and had just three errors in 41 games for Triple-A Iowa last season. He batted .280 with 18 RBIs for the I-Cubs.
C Jose Felix (5-10, 198, 24) —Making his Triple-A debut after playing for Mexico in the World Baseball Classic. Felix spent the past two seasons with Frisco, hitting .260 with seven home runs in 2012.
C Eli Whiteside (6-2, 220, 33) —Played in 82 games for the Giants in 2011 and 12 more last season. Whiteside has 489 at-bats in the big leagues, but he hit .224 in the minors last season.
1B Chris McGuiness (6-1, 210, 25) — A Rule 5 draft pick who spent spring training with the Indians before returning to the Rangers. He batted .268 for Frisco last season, belting 23 home runs, and will make his Triple-A debut this season.
SS-2B Greg Miclat (5-8, 180, 26) —Switch-hitter, who could see action at shortstop, second base and even third, was the final piece of the Rangers’ 2011 trade with Baltimore that involved catcher Taylor Teagarden. Miclat played in just 37 games in 2012 because of a wrist injury — batting .275 with 10 doubles in 109 at-bats — but he finished the season with Round Rock
3B Mike Olt (6-2, 210 24) — The No. 2- ranked prospect in the Rangers’ organization, Olt grew up on the East Coast as a fan of Derek Jeter and the Yankees. He will move around on defense, as he tries to develop fielding skills at first base and in the outfield. Olt smacked 28 homers in 95 games for Double-A Frisco last season, and he’s the best power-hitter with the Express, manager Bobby Jones said.
SS Jurickson Profar (6-0, 165, 20) – The consensus No. 1 minor-league prospect, Profar might already have joined a big-league club that didn’t have Ian Kinsler and Elvis Andrus on its roster. Profar can hit (.281, 26 doubles, 14 HR and 62 RBIs in Double-A last season), but he also committed 22 errors at shortstop. Profar, from Curacao, played for the Netherlands in the World Baseball Classic.
2B Yangervis Solarte (5-11, 195, 25) — Jones calls Solarte one of the top prospects in Round Rock. Last season, Solarte batted .288 with 28 doubles and 11 home runs for Round Rock. Solarte falls in a similar category with Profar, as in he plays in the infield, where the Rangers are stocked with talent. He will play at second, third and in the outfield in his eighth minor-league season.
Jim Adduci (6-2, 210, 27) — Had one of the best springs at big-league camp, hitting .388 with nine RBIs in 49 at-bats. Jones said Adduci’s ability to play multiple positions and run the bases (159 steals in the minor leagues) make him a solid fit.
Engel Beltre (6-2, 180, 23) — Considered one of the best fielding prospects in the Rangers’ system, Beltre should be a fixture in center field. He batted .261 at Frisco last season — strking out 118 times in 133 games — but his speed and range make him an eye-popping fielder who could join the Rangers this season.
Joey Butler (6-2, 220, 27) — The Express’ lone PCL all-star last season has been with the team since being called up from Frisco in 2011. Since then, he’s hit 32 home runs and batted .320 (2011) and .290 (2012). Butler had hoped to make the leap to the big league club this spring, but was ear-marked for Round Rock in mid-March.
Aaron Cunningham (5-11, 195, 26) — In 222 games over five big-league seasons, Cunningham has a career batting average of .219. A reliable fielder, he signed with the Rangers in November.
