We have made it to another week of the 2020 MLB season. Despite the fact that a large chunk of teams were affected by the recent and outbreaks, which resulted in nearly , the league kept chugging along with games elsewhere last week. The have remained sidelined since July 29, and we still don't know when the team will be able to return to play.So, we're going to take a closer look at some of the biggest stories from the latest batch of games, and give each one a buy/sell decision. What are you buying and selling after this week in baseball? Feel free to share your thoughts on Twitter with me . Now, let's get to it: Buy: Tatis hot at the plateIn his second season in the bigs, shortstop Jr. has been off to a hot start. Entering Tuesday, the 21-year-old leads the league in total bases (52) and is tied with ' for most home runs, with eight. Five of those homers came in the last week for Tatis and two of them happened in the same game on Saturday. On the season, he's batting .328/.408/.776 with a 1.184 OPS (229 Kris Bryant Jersey OPS+).Entering play on Tuesday, Tatis is carrying an eight-game hitting streak dating back to Aug. 2, and it includes three multi-hit games. Over the last six games, he batted .435 with seven runs scored, a double, six home runs and nine RBI. The Padres' phenom became the ninth different player, 21 or younger, in history to hit a home run in four consecutive games, and the first since ' Jr. last year. He also became the first to hit 30 home runs and record at least 20 steals in his first 100 games played. There's only eight other MLB players in history who have hit at least 30 homers in their first 100 MLB games: , , , , Aaron Judge, Mark McGwire, and Rudy York. sTatistics through San Diego Padres (@Padres) Through 100 career games: Fernando Tatis Jr. - .320/.385/.625, 76 R, 17 2B, 7 3B, 30 HR, 70 RBI, 20 SBMike Trout - .302/.360/.497, 72 R, 21 2B, 3 3B, 15 HR, 52 RBI, 27 SBAlex Rodriguez - .283/.315/.488, 53 R, 23 2B, 2 3B, 14 HR, 58 RBI, 9 SB Ryan M. Spaeder (@theaceofspaeder) To add to his already impre sive 2020 resume, Tatis is the league's Carlos Zambrano Jersey best average exit velocity (97.6 mph), hard hit percentage (67.4) and second-best (.487).Tatis excelled in his rookie campaign, so much so that he was able to garner some votes for the NL Rookie of the Year Award, even after his season was cut short due to a back injury. His improvement from Year 1 to Year 2 has been a lot of fun to watch. He's got the same power, speed and strong defense we saw in 2019 -- the strikeouts are still high -- but now he's begun to sharpen up at the plate, showing a bit more patience. I'm buying Tatis' hot start. He's already become of the most electric talents in baseball, and I don't think it'll be long before he's one of the faces of the sport. Sell: Worries about the Reds after so-so startThe loaded up this offseason with the hope of a return to contention, but after 16 games, the club is just hanging on to its second-place spot behind the in the NL Central. Entering play on Tuesday, the Reds are 7-9 on the season and own a .500 winning percentage for their last 10 games.Reds outfielder , acquired in the offseason, is still continuing his unbelievable start in Cincy (we highlighted this ), but the rest of the lineup hasn' Brandon Morrow Jersey t impre sed as much offensively. is in a slump, has only played seven games this season due to injuries, was 2-for-12 last week and is one of the few Reds batting above .240. As far as the rotation goes, and have been solid and has been decent but the Reds have only scored a total of six runs in the three games Castillo has started.The bullpen is where the Reds need to get some help. Like everything in this abbreviated 2020 season, any weakne s needs to be addre sed almost immediately. Reds reliever hasn't looked like his usual self this season and sports a 16.88 ERA (2.92 ERA in 2019). As of late, , Amir Garrett and have been solid but altogether, the Reds relievers ERA is 7.77, the second-worst in baseball. No other reliever has been lights-out this season, and with the shaky performances thus far this season, the bullpen is in need of some reliable arms.This doesn't look that great on paper for the Reds right now, but I'm going to sell on any worry. It's still early, they're not that far below .500 and can still climb back up to hold the second-place division spot or even, if things start clicking again on offense, they can try to overtake the Cubs for first. Plus, there's going to be the . All that being said, the Reds will still need to play better but ultimately, if I'm to go off of right now, they're still in good shape for a postseason berth.Buy: A's looking like a real contenderLast week, we asked the question of whether we buy or sell the between the and the . Well, now, we're asking the question of whether we buy or sell the A's as a true World Series contender. After a nine-game winning streak (the Ron Santo Jersey longest winning streak in baseball this season) saw its end to the on Monday, the A's have extended their first-place AL West led over the Astros to four and a half games. According to Sportsline, the A's 2020 World Series odds jumped from a 3.6 percent chance to win it all to 7.9 percent. Last week, the Astros were 60 percent to win the division and the A's at 33 percent. Now, after Oakland's impre sive week, the A's are 80 percent to win the division. Our own Mike Axisa broke down with their recent win streak.The A's swept the Astros in Houston, as part of their winning streak this week. Sidenote: both clubs got into a during that series. Meanwhile, the Drew Smyly Jersey Astros have lost their last five of six games. There's still some time for the Astros to jump back into the division race and make this a two-team race like we discu sed earlier, but based on Oakland's recent succe s, now we have to discu s whether this team is the real deal for a World Series title this year. I'll say yes, I'm buying this. Here's why.The A's have been led by a steady rotation and bullpen, two things that we are seeing teams struggle with all acro s the league right now. A big factor is obviously the shortened season itself and the quick second spring training, not allowing pitchers the normal time usually given to ramp up their workload. We've seen more pitcher injuries than normal so far this season. But, Oakland pitching has managed to stay healthy and reliable. Right-hander has been solid on the mound for the A's. In his last two starts, he took home the win and recorded 14 strikeouts, four walks, six hits and a 0.64 ERA acro s 14 innings. Fellow rotation mates (quality starts), (earned his first MLB win), (reliable so far) have also contributed to the club's early-season succe s. Entering play on Tuesday, the A's have the third-lowest ERA (3.10) in the league, trailing only the and .
