Josh Reddick - I guess we should finally discuss Josh Reddick, huh? Reddick is exhibiting a severe increase in plate discipline this season by any measure (chase rate, swinging strike%, contact rate, swing%, BB rate, K rate), and it's coincided with a nice rebound in ISO and a career-best LD rate as well. He's hitting 305/380/511 after a 3-4 (with a double and a steal) day on Sunday, and he's basically performing at the level of a #2 OF in standard-sized leagues right now. The BABIP has even bit quite a bit low, so it isn't like there is any regression to be expected. The complete statistical evidence of a change in approach has me sold on the hot start here...I do believe it is sustainable.
Mitch Moreland - Moreland had two hits for the 3rd straight game on Sunday, and he's now hitting 307/370/511 on the year. That line jumps to 313/374/572 against RHP, yet he is still owned in less than 15% of leagues on ESPN. He's posting the best chase rate of his career, and his hard contact rate is above 400% for the second straight season. He's a deep league starter for sure, a daily play guy against RHP, and he merits some consideration as a CI in more shallow formats as well.
Mike Pelfrey - Apparently with some guys it just takes a year or 10 to figure out how to pitch. Pelfrey tossed 8 shutout innings against the Brewers Sunday, allowing 7 singles, a double, and a walk with 7 K's to move to 5-2 on the year. The good news for Pelfrey is that he has improved velocity (by almost 2 full mph), is allowing less hard contact than ever before, and has a massively increased GB rate this season. The bad new, at least for Pelfrey and the Twins, is that he still doesn't miss bats (career-worst contact rate against this year, and that's saying something) and his control has merely gone from worse to poor. There may be enough good here that I can squint and see a spot starter, but he still looks like a 4.00 ERA guy at best to me.
Brock Holt - Holt was 5-10 with 3 walks over the weekend against Oakland, and with a line drive rate (35.5% in 2015) and walk rate that continue to climb combined with a chase rate that continues to drop, he has the look of a legitimate .300 hitter. There's very little power and just a bit of speed here, but particularly in OBP formats he can be a very valuable lower-tier member of your offense with his positional flexibility (he could be eligible everywhere but C depending on your league rules) and his AVG/OBP chops.
Carlos Correa - The future is now, as the Astros have made the decision to call up Carlos Correa and put him right into the starting lineup on Monday. The Villar/Marwin Gonzalez platoon is going to be completely devoid of value now, and as for Correa I believe him to be worthy of an immediate pickup in all formats. He's a potential .300-30-15 bat at a weak position coming off of a 332/402/602 line through 52 games at AA and AAA. Sure, he may struggle, but I'd be surprised if he doesn't at least perform as a top-15 SS the rest of the way, and even that low bar makes him starter-worthy in just about every format.
