Cole's missed start begins a tough stretch for the bullpen

The first game of Tuesday's doubleheader looked precisely like what Houston would have wanted on Monday night to erase the memory of the loss to Baltimore. Greinke went six innings while allowing just two runs, and he got some run support behind him, then the bullpen had three clean, quiet innings to shut things down.

Then, the first of Houston's bad luck started. Gerrit Cole's hamstring gave him discomfort during warmups for the second game of the doubleheader, and he would get scratched. Houston's bullpen, who had just used three of their arms in the first game, had to scramble for a full nine innings. While the collection of relievers allowed four runs, it was Houston's offense that disappointed in the loss, the first of a five-game skid.

One step forward, two steps back

One of the most frustrating parts of the losing streak was that multiple times Houston worked to get the momentum back in their favor with a successful offensive inning, only to see their opponent score in the next half-inning to halt that momentum in its tracks. While credit is due to the White Sox and A's who did a good job against Houston's pitching, it was not a normal thing that the Astros typically experience.

Look no further than the series finale with the White Sox. After trading blows back-and-forth most of the game, Houston received a big momentum boost with a game-tying two-run homer by Jose Altuve in the top of the eighth. Ryan Pressly, who had allowed just ten earned runs in the entire season so far, was on the mound in the bottom of the inning to hold things there and give the offense another crack at going ahead in the ninth. Instead, he had his worst inning of the season, allowing a grand slam which ultimately lost the game.

That was just one example where it seemed like Houston had the odds tilted against them. While the bullpen is still an area of concern for the Astros, this week was not merely their bad performers going out and letting the team down. It was an all-around tough week for all of Houston's pitching, and a compressed stretch for their bullpen to cover didn't help. Even Aaron Sanchez, who had been terrific in his first two starts with the Astros, had a tough game where he allowed six runs.

Losing streaks are part of the game

While losing streaks are incredibly frustrating, especially when a significant factor of them is only bad luck combined with not playing up to potential, they are bound to happen in a 162-game baseball season. Pair that with a team that's on 100-win pace whose losses are few and far between, and a losing streak of a few games can be perceived a little more drastic than they are. Had these losses been peppered throughout other weeks, these would have easily been games you look at and say, "Oh well, it just wasn't their day."

Things finally took a turn back to normal on Sunday when a good pitching day paired up with some timely offense, resulting in a much more standard game of Astros play which got them back in the win column. Luckily, Gerrit Cole looks to have avoided anything serious with his hamstring and should make his next start on Thursday against the Tigers at home.

They also activated Brad Peacock over the weekend, which means he will provide Houston's bullpen not only with a fresh arm but one that has been successful as a reliever in the past. More reinforcements for the bullpen appear to be on the way with Josh James working through his rehab tasks to make a return before the playoffs.

At the end of the day, a losing streak in August is not nearly as worrying as one in September. Considering the remaining schedule, I would fully expect that Houston goes on a considerable winning streak before another losing streak, and still have a significant chance of locking up the division early, finishing with 100+ wins, and potentially the best overall record.
