Week 2 Fantasy Stockwatch

Can Chris Volstad take advantage of an opportunity in Florida? Is Clay Buchholz destined for the minors? Our Eric Mack touches on that and more in his latest Fantasy Stockwatch.

Every Monday we'll take a look at the Fantasy Baseball gainers and decliners in our Fantasy Stockwatch.

Since most minor league call-ups won't be in play for at least a month, you have to scour Fantasy waiver wires for big leaguers this time of the year. Picking up the wrong hot hand, or dropping the wrong slow starter, could lead to a season of regret. We don't think you should make a drastic change if your team got off to a bad start in Week 1, but there are some players we think can be bought or sold before they go boom or bust -- including one potential minor leaguer ...

	Chris Volstad, SP, FLA The Marlins had enough of Rick VandenHurk on Sunday, sending him all the way back to Double A. Ricky Nolasco will likely move up from his April 13 rotation debut to start Friday, April 11 now. But the more significant news is the huge opportunity in front of Volstad. He is the Marlins' top pitching prospect and warrants an early waiver claim in all NL-only and long-term keeper leagues at this point. If Volstad (six innings, two runs in his first Double A start) doesn't get the nod, it could go to Burke Badenhop (six innings, two runs in his first Double A start). Badenhop was one of the prospects the Marlins received in the Miguel Cabrera/Dontrelle Willis blockbuster.
	Brandon Lyon, RP, ARI Closers are always a mercurial beast and Lyon is the latest example. Jose Valverde's replacement has a great contender to close games for, especially when you consider that solid starting rotation that figures to get him a lot of save chances on a week-to-week basis. Lyon blew two saves in the season's first week and was coming off a bad spring to boot. Closer-of-the-future Tony A. Pena should be picked up as a flier at this point, while Chad Qualls is also an option to close. Qualls got the save in extra innings Sunday after Lyon failed.
	Edinson Volquez, SP, CIN Volquez (VOL-kez) wasn't quite as dominant as fellow Dominican Dandy Johnny Cueto (Kway-to), but he was solid in his own right and will get a lot of residual owners picking him up because they missed out on Cueto. Volquez was once compared to a young Pedro Martinez, but a lack of command has plagued him -- perhaps until now.
	Clay Buchholz, SP, BOS Buchholz flashed his talent with seven strikeouts in five innings in his season debut, but a bad spring and the presence of Bartolo Colon might give the Red Sox a reason to pull back on their talented young right-hander. Colon allowed just one hit in his five-inning Triple-A debut last week, so he could prove No. 5 starter worthy if the Red Sox decide Buchholz could use more time in the minors.
	Justin Upton, OF, ARI One of this writer's biggest regrets this winter was giving this 20-year-old phenom just 14 homers and 14 steals in our preseason projections. We know how talented he really is, no question. He was No. 2 among our overlooked sophomores behind teammate Mark Reynolds. But we didn't see Upton's raw talent coming out of the gate this impressively. He hit three homers in three games, joining Willie Mays and Mel Ott as the only 20-year-olds to do that since 1900. He is available in 19 percent of CBSSports.com's leagues.
	Juan Pierre, OF, LAD We agree Pierre is merely the Dodgers' fourth-best outfielder behind Matt Kemp, Andruw Jones and Andre Ethier, but we didn't really how little of an impact Pierre was going to have in Week 1. Pierre is about as worthless as you can get in non-Rotisserie leagues at this point. Cutting him in all Head-to-Head leagues for a better run producer is advised. He needs a trade and his contract makes that unlikely at this point.
	Jose Lopez, 2B, SEA This Lopez has been a low-end Fantasy second baseman for years, but you likely need to be reminded he is just 24 years old. There is pop in his bat -- as he has shown us this past week. If you are doing without a Kaz Matsui, Ty Wigginton or Freddy Sanchez right now, take a flier on this potential breakthrough Mariners middle infielder.
	Barry Zito, SP, OAK Zito had a bad spring, but in Year 2 you had to figure he would be able to improve at least a little bit over last season's disaster. So far, it is more of the same for the $127 million erratic lefty. Zito is not a guy to cut yet in most leagues, but the notorious slow starter is not someone to trust in your starting lineup right now either. Even worse than the reports of a lack of velocity -- not that the curveball specialist needs 90 mph stuff -- is Zito has a putrid supporting cast in San Francisco. He could be a 15-game loser.
	Manny Parra, SP, MIL The coming weeks are going to be a lot about the return of phenom Yovani Gallardo, so Parra will fly plenty under the radar. He had a solid first start and shouldn't be the one to lose his rotation spot once Gallardo returns. Carlos Villanueva can slot in the bullpen if the Brewers decide to stick with Parra. He is a Rookie of the Year candidate as a full-time rotation member on a contending team.
	Eric Chavez, 3B, OAK There was injury-risk sleeper potential with this A's third baseman, who is still just 30 years old. But he needed a second epidural injection into his surgically repaired spine and will be out at least another month. If your league doesn't have DL spots, we suggest you drop this waste of roster space for a younger, healthier talent like the aforementioned Mark Reynolds. We type Reynolds is a sleeper for the 100th time, he just goes deep off Manny Corpas for a go-ahead two-run homer in the ninth. Mark Reynolds, folks.
	Xavier Nady, OF, PIT Nady is not as good as his three homers in Week 1 suggest, but he is a streaky power hitter worthy having in all Fantasy leagues when he is going well. His ownership has nearly doubled since his pair of homers on opening day. The 29-year-old has always had 30-homer potential, but he has not been able to have a 500 at-bat season in the big leagues. If he is able to stay healthy, we might finally see Nady's best. Pick him up just in case this is his year to break out.
	Mike Hampton, SP, ATL We know the ones that won't bother to drink our Mark Reynolds Kool-Aid: The ones who feel betrayed by the hype laid on Hampton's return by yours truly. We can't blame you. We were fooled by Hampton and realize we should not have relied on his ability to get or stay healthy. Hampton was yanked right before his season debut and got the hook by almost 50 percent of his Fantasy owners.

Stock advisor

Chuck Morrell, Colorado Springs, Colo.: I have Garrett Atkins starting at third, but I'm torn between Chone Figgins and Evan Longoria as my backup. What would be the smarter choice?

Emack: Since you have Figgins as a backup, we are assuming you are in a Head-to-Head league with reserves. Atkins is not someone we would advise ever sitting for Figgins, so take a chance on the elite minor league prospect in Longoria. Longoria should arrive around June 1 and impact all Fantasy leagues -- despite his 0-for-11 start back in Triple A.
