Giants ace Madison Bumgarner recently changed representation, MLBTR’s Tim Dierkes reports on Twitter. The outstanding southpaw has hired Excel Sports Management as his agency.

Bumgarner, 26, has gone from being a quality young pitcher to a bona fide top-of-the-rotation star. He’s ended each of the last three seasons with a sub-3.00 ERA, and has increased his innings output and K:BB ratio in each successive campaign. Last year, he spun a career-high 218 1/3 frames and struck out 9.6 while walking only 1.6 opposing batters per nine.

Of course, the Giants were able to lock MadBum into an early-career extension just prior to the 2012 season. That pact largely lined up with the guarantees given to other impressive young starters, but did set a record for 1+ service-time pitchers when it was signed.

Now, of course, the contract is an unquestionable steal for San Francisco, which controls Bumgarner through 2019 via a pair of $12MM options. That would take Bumgarner through his age-29 season, meaning he could still hit the open market at a reasonably young age — or, of course, consider an additional extension.

Bumgarner joins an already-impressive stable of pitchers with Excel, including Clayton Kershaw, Zack Greinke, and Masahiro Tanaka. As always, you can find information on player representation in MLBTR’s Agency Database.
