Baseball Commissioner Bud Selig says the sport will wait until after the season to study whether the rule preventing pitchers from using pine tar should be changed.

New York Yankees pitcher Michael Pineda was suspended for 10 games Thursday, a day after umpires found pine tar on his neck during a game against Boston. Pineda said he was trying to get a better grip on balls on a cool night, and pitchers say they suspect pine tar use may be routine — although usually discreet.

Baseball rules prohibit pitchers from using foreign substances.

— The Pittsburgh Pirates have put closer Jason Grilli on the 15-day disabled list with a strained left oblique and called up right-hander Jared Hughe. Grilli has already blown three of seven save chances this season and has a 4.50 ERA after becoming an All-Star for the first time last season.

— The Texas Rangers have activated third baseman Adrian Beltre from the 15-day disabled list and placed third baseman Kevin Kouzmanoff (KOOZ'-mah-nahf) on the DL with a sore back. Beltre was hitting .286 with four RBIs in eight games before straining his left quad. Kouzmanoff left Tuesday's game in Oakland with back tightness.

— The San Diego Padres have put third baseman Chase Headley on the 15-day disabled list due to a strained right calf suffered in Thursday's win over the Nationals. Headley is hitting .186 with two homers and seven RBIs.

— Angels manager Mike Scioscia (SOH'-shuh) says setup man Joe Smith will step into the stopper role until Ernesto Frieri (free-HER'-ee) works out his problems. Frieri is 0-2 with a 9.35 ERA in 10 appearances this year.

— The Chicago White Sox claimed right-hander reliever Hector Noesi (noh-EH'-see) off waivers from the Texas Rangers and expect him to throw a bullpen session for pitching coach Don Cooper on Saturday. Noesi allowed 10 runs in 6 1/3 innings for the Rangers in five relief appearances.
