We’re halfway through the season, and while you’re still mostly looking for the best players you can find, specific needs become more of a factor in roster moves — for you and others in your league. You might be about to get a nice haul from the person who is suddenly trying to add 50 steals.BuyKyle Stowers, OF, MIAStowers started the year on the IL and seemed to need at least a month to figure things out again after he returned. He was chasing a ton at the start of the year with a 36.7% O-swing rate through May, but has since settled to just under 30% (league average is 32.7%). That drop has coincided with his return to being the player he looked like last year. His barrel rate is an excellent 17.3% in that stretch, which would look like an outlier hot streak if not for last year’s 19% clip. His slash line is .235/.333/.506 in June, compared to .221/.303/.360 before then. The full-season numbers still look pretty ho-hum, but I believe in the good version more than the bad.Lars Nootbaar, OF, STLIt’s only 20 games, so I’m trying to temper my excitement, but I’m seeing the version of Nootbaar I’ve been waiting for. He’s always been selective, but now he’s one of the most patient hitters in the league. This has not led to a strikeout issue because he also has elite contact skills. Add in solid power, and you have a really good hitter who is a beast in OBP leagues. The .294 average will come down — that’s 50 points above his career mark — but his combo of patience, power and contact is hard to find.Vladimir Guerrero, 1B, TOROr, what if you took Nootbaar, but you gave him more power and cut his K rate in half? That guy would easily be a top-10 hitter, right? Usually, but it’s been a weird year for Vlad. The hit tool is still elite, but four homers in half a season? He has an unlucky 4.8% HR/FB rate (his hit chart shows five doubles that look like they should have left the park), but that’s not the entire story. He’s hitting more grounders than usual, and it’s only gotten worse over the past month. His ground-ball rate is 53% in June, and he’s slashed an abysmal .195/.234/.264 during that stretch.And yet, he still has elite bat speed and an excellent strikeout rate. His xwOBA of .346 indicates that he can still be a productive hitter even with this swing. This is more guess than analysis, but the All-Star break could give him a moment to get back to himself.Landen Roupp, SP, SFGA 26.2% K rate, 8.2% walk rate and 0.52 HR/9 — these are second-tier ace numbers. A .320 BABIP is a little high, but it shouldn’t be enough to throw everything off. So why does Roupp have a 4.07 ERA? His 66.4% strand rate is sixth-worst among qualified pitchers. His FIP is under 3.00, and other ERA estimators are in the low-to-mid 3s. He’s a really good pitcher disguised as a bland one.SellChase Meidroth, 2B, CWSMeidroth is one of those nifty players who won’t give you everything you need, but he can patch things over in average and runs. The niftiness, however, will not hold up with his current approach. Meidroth, like Nootbaar, leverages his excellent contact skills to see a lot of pitches. However, that has lifted his strikeout rate more than his walk rate — you’d feel more comfortable with a 24.8% K rate from a power hitter. Still, the overall line looks good because he sports a .362 BABIP, but that’s hard to keep up if you’re not smoking the ball, and Meidroth isn’t a smoking-the-ball kind of guy. The xBA of .227 suggests the actual BA of .276 is inflated. Maybe the K rate drops for some balance, but I wouldn’t bank on it too heavily.
