If you compete in a head-to-head league with a three-week postseason, your league is approaching the halfway point of the regular season.

As usual, the waiver wire at times has been more prolific than Kanye West, but often more dangerous and frustrating than Kim Kardashian. (Beware, Kanye. Beware.)

Regardless, we are back (belatedly) with more waiver-wire picks if you're looking for hitting help. As always, the following players are available in more than half of the leagues on ESPN.com. This week's batch is available in more than 85 percent of the ESPN formats.

-- Wilin Rosario, C, Rockies (owned in 14.7 percent of the ESPN leagues): The 23-year-old rookie is batting only .233, and he's a strikeout waiting to happen (35 Ks in 120 at-bats). But he also has some Coors Field-aided pop. Rosario has nine homers, 18 runs and 25 RBI -- a 600 at-bat pace of 45 homers, 90 runs and 125 RBI. OK, he'll probably never hit 45 homers or drive in 125 runs, but Rosario was productive in the minor leagues. Again, his average was an issue (.267), but he racked up 61 homers, 216 RBI, 198 runs and a whopping 354 Ks in 1,469 at-bats. At catcher, you can overlook the poor batting average and big strikeout numbers when that much power is included.

-- Juan Pierre, OF, Phillies (11.1 percent): At 34, Pierre has been much better in his first season in Philadelphia than he was in 2010 and '11 with the White Sox (when he batted .275 and .279, respectively). He's hitting .322 with 23 runs and 11 steals in 180 at-bats. Since May 25, Pierre is batting .377 with 10 runs and five steals in 53 at-bats. You know he won't provide any power (16 homers in 7,003 at-bats), but if you need to improve your team's batting average and/or stolen-base numbers, Pierre might be the best option on the wire.

-- Jerry Hairston Jr., 2B, Dodgers (7.7 percent): He's batting .356 with two homers, 15 RBI and a .938 OPS in 104 at-bats. Since May 27, the 36-year-old is hitting .391 with 10 RBI in 46 at-bats. Since a knee injury will keep regular second baseman Mark Ellis out until at least late July, Hairston will continue to get plenty of at-bats. He's likely to suffer a hefty drop in batting average (his career norm is .261), but he has the potential to steal 20 bases, and his recent play makes him worth considering in the infield. In ESPN leagues, Hairston is also eligible at third base and the outfield, though I would only start him at the latter position in NL-only formats.

-- Trevor Plouffe, 3B, Twins (7.1 percent): His average (.217) won't get your attention, but his power will (nine homers and 17 RBI in 129 at-bats). In 456 at-bats in the majors, Plouffe has 19 homers and 54 RBI. Those numbers are an improvement when compared to his minor-league track record (15 homers and 73 RBI per 600 at-bats), but Plouffe is certainly worth a look in deeper mixed leagues. In June, he is batting .387 with four homers, seven runs and nine RBI in 31 at-bats. In ESPN formats, he's also eligible at shortstop (where his pop should be a welcome addition) and the outfield.

-- Ben Revere, OF, Twins (4.4 percent): Since he was recalled from Triple-A in mid-May, Revere has had a hit in 16 of his 20 appearances. This month, he's batting .368 with nine runs and five steals in 38 at-bats. On the season, he's hitting .327 with nine steals in 101 at-bats, and he stole 34 bags as a rookie in 2011 (when he hit .267). Don't be surprised if Revere keeps his average above .300 -- he is a career .326 hitter in the minors -- and with his speed, he can start in most formats. If you need to add power to your outfield, you'll have to look elsewhere, though. Revere has yet to hit a home run in 579 career at-bats in the big leagues.
