Yes, he'd look good in a Phillies uniform.
Here's why you can't blame Amaro and the Phillies for letting Grilli walk: He wasn't even the best pitcher on the triple-A Lehigh Valley team in 2011 and he was 34 years old with a career 4.74 ERA in eight big-league seasons.
He pitched great during his one season with Lehigh Valley, posting a 4-1 record with three saves and a 1.93 ERA in 34 games, but a lot of younger guys who the Phillies were far more invested in pitched great that year, too.
Michael Stutes, 24 at the time, got an early-season promotion and went 6-2 with a 3.63 ERA as a rookie.
Justin De Fratus, 23 at the time, went a combined 6-3 with a 2.99 ERA and 15 saves at double-A Reading and Lehigh Valley. He struck out 99 batters in 751/3 innings.
Phillippe Aumont, 22 at the time, went a combined 2-5 with seven saves and a 2.68 ERA at Reading and Lehigh Valley. He struck out 78 batters in 532/3 innings.
Michael Schwimer, 25 at the time, went 9-1 with 10 saves and a 1.85 ERA. He struck out 86 batters in 65 innings.
Joe Savery, 25 at the time and a former first-round pick, went 4-0 with a 1.80 ERA and two saves in 18 games and showed mid-90s life on his fastball.
Andrew Carpenter, 26 at the time and a former second-round pick, went 5-1 with a 1.79 ERA and struck out 65 batters in 601/3 innings.
Scott Mathieson, 27 at the time, went 2-2 with a 3.28 ERA and five saves. He struck out 83 batters in 821/3 innings.
Mike Zagurski, 28 at the time, went 4-0 with 11 saves and a 2.65 ERA.
That's eight guys, all younger than Grilli, who showed tremendous bullpen promise in 2011.
Here's the Phillies' problem: The eight guys mentioned above went into the weekend with a combined 5.13 ERA pitching for the Phils in the big leagues. Not one of them has become an established big-leaguer.
