There hasn't been much change when it comes to closers recently. It's just a matter of time before there is a move somewhere. One situation to watch is the White Sox with Sergio Santos.
Santos has been one of the pleasant surprises and been a great find off the waiver wire. He didn't allow a run in 11 2/3 innings in April. He allowed just four earned runs in 14 innings in May and converted 8 of his first nine saves.
Santos began June with three consecutive saves, but has been very shaky the last three games. He blew one save, lost a game, and notched a save despite giving up one run, two hits, and a walk in one inning.
In the three games, Santos has pitched 2 2/3 innings and allowed seven hits, eight runs, walked six and struck out three. He was going to struggle at some point and his job is safe for now.
But Santos is a converted shorstop with little pitching experience. While he has a 10.52 K/9, control has always been an issue and a 5.68 BB/9 could spell doom. He was able to have a 2.96 ERA with a 4.53 BB/9 last season, but pitching in the ninth inning is different. Matt Thornton has pitched better and Chris Sale and Jesse Crain are options.
