This has been a pretty exciting weekend of baseball so far. This game featured two homers by Luis Rivas, which... wow. It also featured a couple of very good defensive plays by the Pirates, a pretty funny moment in which Alfonso Soriano muffed a play in the outfield by appearing to lose the ball in the sun, another excellent performance by Damaso Marte (who has allowed just two runs since April 20) and yet another game-winning hit by Jason Bay.
There's been a lot of hand-wringing recently about Bay's ability to produce in the clutch, some of which was probably held over from 2006, when he posted a low batting average with runners in scoring position. (It doesn't look like any big deal now, but as I recall, people complained about it quite a lot then.) It's worth pointing out that, before today, Bay's career line was .282/.378/.517. With runners on, it's .282/.386/.506. With runners in scoring position, it's .283/.398/.526. With runners in scoring position and two outs, it's .262/.404/.500. The only split that's been an issue is with bases loaded, where he's hit .226/.263/.650, but that's in only 62 at bats.
In other words, there's absolutely no problem here. Nothing to see, move along.
