Waiver Wire: Tuesday, April 20

We’ll do a tiered approach here. It’s what we do.

Ervin Santana | SP | Los Angeles (54% owned)
While the ownership numbers may be perplexing (he’s owned in all of my leagues), there’s reason for hope when it comes to the other Santana (soon to be the other other Santana). Most of the signs are looking good for Santana – his strikeout rate is up, his walk rate is down, and he’s even sporting a career-high ground ball rate. The only worrisome thing might be the reduced effectiveness of his slider as measured by his linear weights. It can’t be the half-MPH that he’s lost on the pitch, can it? In any case, he’s benefiting from a career-best 38.9% contact rate on pitches outside the zone, which doesn’t seem like it can continue when seen in the face of his career 58.4% rate. Perhaps people will start whiffing a little more on his pitches in the zone (98.8% !). It’s a strange mix right now, but since he’s healthy he should be on more rosters.

Casey Kotchman | 1B | Seattle (6% owned)
Paradoxically, it took a move to one of the toughest parks in the league for Kotchman to break out his career-best ISO (.310). Of course, that number only stabilizes around 450 plate appearances, so we shouldn’t read too much into it. Instead, let’s look at the numbers that stabilize the quickest: swing rates. Because they are based on pitch-by-pitch data, swing rates have a larger sample size in the early going. Kotchman is swinging at a career-low rate (35% this year, 45.4% career), and this has lead to the best K/BB ratio of his career (1.5). The strikeout percentage is below 10% and good for 25th-best in the league in the early going. That sort of ueber-patience seems to be serving him well. Don’t buy into the power, but the patience may end up leading to a good batting average and good run production, given the dearth of offense in Seattle.

Bud Norris | SP | Houston (5% owned)
(I know, the tiers are a little off.) Ever since Cistulli wrote this masterpiece about Norris’ nice outside-the-zone whiff rate, he has been an interesting character here in the green-and-eggshell. The secondary statistics for Norris are actually sort of frightening – he has an otherworldly strikeout rate (14.09 K/9), a disastrous walk rate (8.22 BB/9), and an insert-bad-adjective here groundball rate (23.8%). Group these rates with his zero HR/9 and you have an early-season special – an ERA (3.52) between his FIP (2.60) and his xFIP (4.03). That might be a strange feat – if it were to happen over a full season. I’d say some of those fly balls will begin to leave Minute Maid park shortly and that the xFIP is the number to follow, but that’s still a decent number that deserves attention. Maybe Norris will split the difference between his good start and bad start the next time he climbs the hill.
