Here are some notes regarding some Major League pitchers:

– Red Sox starter Daisuke Matsuzaka will definitely undergo Tommy John surgery probably next week reports Jon Heyman of Sports Illustrated. Dr. Lewis Yocum will perform the surgery.

– Phil Hughes threw about 50 pitches in a simulated inning yesterday according to Marc Carig of the Newark Star Ledger. The right hander will face batters in live batting practice on Saturday in Anaheim. Hughes is hoping that throwing live BP on Saturday could be the final step before going on a Minor League rehab assignment.

– Mariners sensation Michael Pineda is at 70.1 innings so far in the season, and ESPN’s Buster Olney wonders if the Mariners will limit the usage of Pineda from now on. Usually the teams that apply those kinds of guidelines give their young pitchers around 170-175 innings of workload per season, so Pineda would have about 100 innings left for the final four months of the season says Olney.

– With Matsuzaka undergoing season-ending surgery, Kevin Milwood’s chances with the Red Sox went straight up, but the right hander had a rough start at Triple-A last night. Millwood lasted only 2.2 innings allowing four runs snf five hits for Triple-A Pawtucket last night, reports Peter Abrahams of the Boston Globe. The 36-year old has a 5.79 ERA in four starts in the minors for the Yankees and Red Sox this season.
