It wouldn't be a Brewers broadcast without a mention of the Crew's struggles with RISP, especially with 2 outs and RISP.
(Actually, I don't know if they're still talking about this--it feels like weeks since mlb.tv has given me Brian and Bill.)
Anyway, it is technically true that the Crew is below average in this department. With RISP, the Crew is a bit below league average, with an sOPS+ of 97. (sOPS+ is a handy Baseball-Reference stat meaning OPS relative to league average for that situation. 100 is average, less is worse, more is better.)
Look at RISP with two outs, and it's worse: That's down to 86. The worst offenders are Weeks and Kendall, both of whom are OPS'ing under 500, though Braun is at a mere 590. We should probably bench him, or at least pinch-hit for him in clutch spots.
However, there's an interesting contrast if you keep hunting through the splits. Broadcasters love to talk about 2 outs/RISP because it is a proxy for clutch...but it's only a proxy. Obviously, there are important moments in a game with less than two outs, and key at-bats without runners in scoring position.
One way to measure them is by leverage (details here), which takes into account the base/out situation as well as inning and score. (Bottom of the 9th in a one-run game is pretty important, even with the bases empty.) Despite the numbers above, the Brewers are above average in high leverage situations. Also surprising, Braun is among the best on the team, with an OPS of 881. Prince is dominating in such spots, at 1.203.
Along the same lines, the Crew is above average when a game is "close and late," as well as better than the norm in one-run, two-run, three-run, and four-run games. (Just below average in tie games, though that's kind of meaningless, since a lot of games are ties in the early innings, which is hardly the definition of clutch.)
Of course, many of these numbers come in relatively small samples--Prince has had 45 high-leverage at-bats, and the team as a whole has had fewer than 400 PAs with 2 outs and RISP. Given that important situations (high leverage ones, anyway) don't seem to faze the Crew, it may be that the 2 out/RISP numbers will come around, resulting in a few more runs simply due to luck.
Or, I guess, Doug Melvin has signed, drafted, and traded for a bunch of guys who can't handle the pressure. Your call.
