MLB notebook: Rockies pitcher suspended; Astros hurler fined
• Rockies pitcher Nick Masset was suspended three games and fined for throwing a pitch at Braves catcher Evan Gattis on Thursday. Braves reliever David Carpenter was fined for throwing at Rockies outfielder Corey Dickerson in the same game, which featured several ejections, including Colorado manager Walt Weiss. Carpenter subsequently was placed on the 15-day disabled list with a strained right biceps.
• The Red Sox designated outfielder Grady Sizemore for assignment. Sizemore hit .333 in spring training and started in center field on Opening Day when he homered in Boston's 2-1 loss at Baltimore. But in 52 games, he hit .216 with two homers and 15 RBIs.
• The Diamondbacks recalled right-hander Mike Bolsinger and inserted him as the starter Tuesday against the Brewers. The move comes after right-hander Bronson Arroyo went on the disabled list for the first time in his long career. Tests showed Arroyo has a sprained ulnar collateral ligament in his right elbow.
• The Yankees shuffled their catchers, activating Francisco Cervelli from the disabled list and sending John Ryan Murphy to the minors. Cervelli strained his hamstring in mid-April while running out a grounder. He was hitting .188 in five games as the backup to Brian McCann. Cervelli has played parts of the seven seasons for the Yankees, batting .269 with 80 RBIs.
• The Rangers signed veteran Carlos Pena to a minor-league contract in an effort to find help with their top four first basemen on the disabled list. Pena hit .207 with the Astros and Royals last season.
