It appears that I spoke too soon yesterday when I wrote that the Kevin Slowey for Zach Putnam exchange was the only clear trade win for Dan O'Dowd this offseason. This trade win for O'Dowd netted the Rockies an established player and not a prospect like Putnam as from the Red Sox point of view this is a salary dump to clear money for a starting pitcher. This is where you (and I) have to give Mr. O'Dowd and the rest of the front office some credit because even with the Rockies picking up every cent of Scutaro's 2012 salary, getting him for Mortensen is a steal.
Scutaro is 36, so he fits the profile of the type of player the Rockies went after this offseason. He played shortstop with the Red Sox in 2011, but second base is where he fits in with the Rockies. Scutaro hit .299/.358/.423 with seven homers, 54 RBI over 113 games in 2011. He likely peaked in 2009 when he hit leadoff for the Toronto Blue Jays, drawing 90 walks, scoring 100 runs, and posted a 4.5 fWAR. Scutaro had a rough first half in 2011, hitting .259 in the first half, and still posted a 2.9 fWAR. This is hands down the biggest upgrade the Rockies have made this offseason and none of the other moves they've made even really come close.
Mortensen is 26 and was a supplement first round selection (36th overall) by the St. Louis Cardinals in the 2007 draft. He has a 5.12 ERA, 4.7 K/9, and a 3.7 BB/9 in 24 Major League games (13 starts) with the Rockies, A's, and Cardinals.
