If the Sox could get Diaz for Dalbec, I'd be thrilled.
Diaz has had basically three huge blowup games:
May 29 at LAD: 0.1 ip, 5 h, 4 r, 4 er, 1 bb
June 27 at Phi: 0.1 ip, 3 h, 5 r, 5 er, 2 bb
July 5 vs Phi: 0.1 ip, 3 h, 4 r, 4 er, 1 bb
Totals for those three games: 1.0 ip, 11 h, 13 r, 13 er, 4 bb, 2 k, 117.00 era, 15.00 whip
Now, all the games count and these can't just be thrown out. But when dealing with small sample sizes like relievers have, three games like this *totally* skew the season's stats. He's pitched in 44 games and has given up runs in 10 of them. Apart from these three blowup games, his season stat line would be: 39.0 ip, 34 h, 9 r, 9 er, 9 bb, 59 k, 2.08 era, 1.10 whip, 13.6 k/9
Again, those three games count. But closers giving up 4 and 5 runs generally happen over the course of several games, and as bad as those three games were, they only count for three games. It seems like he's just had a few epic meltdowns, which would mean that if you bring him into a game, you'd better have someone else warming in case it starts to go south. But other than these three games, he's been pretty damned good all season long.
