The Mets have called up Daisuke Matsuzaka to New York while sending down John Lannan. Remember Daisuke? He gained fame in Boston while winning 18 games in 2008. Matsuzaka had a 2.25 ERA and averaged a strikeout per inning in Las Vegas so far this year. That is good enough for the Mets to give him a shot.
Does this mean you should? Daisuke will pitch out of the bullpen, meaning it gives him less of a chance to implode, at least in theory. If you play in a league that counts holds, he should be worth an add if he still averages a strikeout per inning. I would take a wait-and-see approach for the time being everywhere else.
The Angels have called up Brennan Boesch to take the place of Kole Calhoun, who was placed on the 15-day DL. The Angels still have Mike Trout, Raul Ibanez, J.B. Shuck, and Collin Cowgill in their outfield, so playing time could be harder to come by for Boesch.
He will provide some nice left-handed power off of the bench for the Angels, but he will not do much for your fantasy team unless he can carve out a more defined role. Ibanez is batting a paltry .163 on the young season, so perhaps Boesch can take some at-bats there. Still, a wait-and-see approach is probably best with Boesch too unless you are in an AL-only league or a 20 team league that starts more than three OF slots.
