Closing Time: Ketel Marte, Jonathan Schoop, Rajai Davis and other adds

Ketel Marte was an obvious play in daily contests on Monday, as were all other Mariners. Big Pelf was on the hill for Detroit, and no special expertise is required when you see a dude with a 1.7-something WHIP listed among the day's scheduled starters. Picking on Pelfrey is a fairly obvious strategy.

Not surprisingly, Marte went 4-for-6 with a pair of doubles on Monday, scoring two of Seattle's seven runs and driving in another. He's now batting .275 for the season with eight steals in 53 games. Marte was understandably mass-dropped back in May when he was dealing with a thumb injury, but he's back on the fantasy radar, owned in just 22 percent of Yahoo leagues. The 22-year-old shortstop was a reliable 20-steal player in the minors, and he isn't going to be a batting average liability. He's approved for use wherever you need a speed boost.

And while we're adding middle infielders...

• Jonathan Schoop delivered his third straight multi-hit game for Baltimore, raising his season slash to .281/.308/.490. He's batting .324 in June and he's homered four times in his last 10 games, giving him 12 bombs for the season. Schoop cleared the fence 15 times in just 86 games last year, so the power is real. He should really be owned in most mixers, but he's still unattached in 50 percent of Yahoo leagues.

• Justin Upton has been refreshingly not terrible in the month of June, slashing .288/.358/.562 with five homers, 20 RBIs and three steals. He hit a pair of bombs against Seattle on Monday, with an extra-inning walk-off included. The key to enduring a season of Upton ownership, of course, is understanding that the experience is a carnival ride of extreme highs and lows. Definitely not for everyone. Check his month-to-month batting averages since April, 2014: .288, .213, .221, .239, .270, .162, .196, .343, .259, .169, .291, .319, .226, .277, .326. Enjoy the current binge; understand that a collapse is coming.

• Rajai Davis swiped another bag on Monday, his tenth in the month of June and No. 21 on the season. Davis is an everyday player for Cleveland these days, leading off and running at will. No reason to leave him un-owned.

• Willson Contreras finally got a start behind the plate for the Cubs, going 1-for-4 with an RBI single in Chicago's 3-2 loss to the Cardinals. Contreras is expected to start two out of every five games, which, unfortunately, isn't quite often enough to make him a must-own in one-catcher mixed leagues. He belongs on a roster in any other format, however, and he should have been long gone in dynasty leagues. Contreras was hitting a ridiculous .350/.439/.591 at Triple-A before his promotion.

• Monday's much anticipated Strasburg-vs.-Kershaw matchup never materialized, because the Nats ace was scratched with a back strain. No reason to panic just yet if you're a Stasburg owner, because it sounds like he should be good to go in his next start.

• Pat Neshek picked up a save for Houston on Monday night, but circumstances were odd. Nothing to fret about, Harris owners.
