Cubs Select the Contract of Righthander Donn Roach, Option Righthander Yoervis Medina to Triple-A

Catcher Rafael Lopez Designated for Assignment

ST. LOUIS - The Chicago Cubs today selected the contract of right-handed pitcher Donn Roach from Triple-A Iowa and have optioned right-handed pitcher Yoervis Medina to Triple-A. To make room for Roach on the 40-man roster, catcher Rafael Lopez has been designated for assignment.

Roach, who will wear uniform number 62, will be the starting pitcher for the Cubs tonight against the St. Louis Cardinals at Busch Stadium.

Roach, 25, joins the Cubs after going 7-1 with a 2.29 ERA (21 ER/82.2 IP) in 14 starts with Iowa this season. He ranks second in the Pacific Coast League in ERA, is tied for first in wins and is tied for fifth with a 1.10 WHIP, thanks in part to only issuing 15 walks in 82.2 innings pitched, an average of only 1.6 walks per nine innings. He has pitched six innings or more in 12 of his 14 starts this season.

The 6-foot, 195-pound Roach made his major league debut with the Padres last season, going 1-0 with a 4.75 ERA (16 ER/30.1 IP) in 16 appearances, including one start. His previous big league start took place last May 18 when he recorded a no-decision in Colorado. He made the jump from Double-A in 2013 to earn a spot on San Diego's Opening Day roster last year before being optioned to Triple-A El Paso on June 3, where he went 4-6 with a 5.24 ERA (45 ER/77.1 IP) in 19 appearances (13 starts) the rest of the way. He was claimed off waivers by the Cubs on November 12, 2014.

A native of Las Vegas, Roach was selected in the third round of the 2010 Draft by the Los Angeles Angels of Anaheim out of the University of Arizona. He was acquired by the Padres for pitcher Ernesto Frieri in 2012, a season that saw Roach earn Single-A California League All-Star honors. Overall, Roach is 39-27 with two saves and a 3.50 ERA (207 ER/532.0 IP) in 140 minor league appearances (81 starts) covering six professional seasons.

Medina, 26, tossed three scoreless outings covering 5.0 innings during his first stint with the Cubs since being acquired from Seattle on May 19. Overall this season, he is 1-0 with one save and a 2.12 ERA (4 ER/17.0 IP) in 15 big league relief appearances between the Cubs and Mariners.

Lopez, 27, is batting .276 (43-for-156) with eight doubles, one triple, no home runs and 17 RBI in 46 games with Iowa this season.
