After yesterday’s fine outing, Clay Buchholz may be a bit less of a buy-low candidate. Going into said start, Buchholz was sporting a foul 6.06 ERA with a 1.65 WHIP to match. FIP, xFIP, and SIERA told a different story, of course; they were 3.07, 2.73, and 2.84 respectively, on the strength of 19 strikeouts against just four walks in 16.1 innings of work. (He’s now got 29 Ks and 7 BBs in 22.1 IP with a 4.84 ERA).
But even with laudatory marks from famous ERA indicators, we’re still dealing with a small sample, and should be digging deeper to determine whether Buchholz is doing anything differently, or whether he’s actually improved over a pretty atrocious 2014.
Based on what I’m looking at, he’s definitely doing things differently.
First, let’s look at some numbers in a table that spans the full width of this text column. (Remember these stats are through his first three starts this year; they do not include yesterday’s game vs. Tampa Bay.)

The first several columns show an improvement in results so far in 2015; the last several columns offer reason to be optimistic that his traditional stats will even out. First, Clay-B has been horribly unlucky on balls in play, as compared to both his career mark and league average, and he hasn’t given up a line drives at a rate—nor does he pitch in front of a bad enough defense—to warrant such a high BABIP. To boot, he hasn’t induced a single pop-up yet this year, whereas he’s generally done so at a league-average rate in the past. Granted, his new ground-ball-heavy approach might lead to fewer pop-ups, but not no pop-ups. A higher rate of converted outs is nigh for ol’ Clayie. (Guessing that nickname won’t stick.)
You’ll also notice that Buchholz is getting more swings on pitches outside of the zone, and batters are making less contact when they swing at those pitches. Hence, a bump in his swinging strike rate. This, in turn, is also what’s helping his K%. Getting hitters to chase pitches out of the strike zone is generally a good thing; it’s definitely a good thing when they’re not even making contact with those pitches.
