Problem: Born in Venice, Ohio, Alson spent much of his childhood on a farm in Morning Sun; when he was a teenager, the family moved to Darrtown. Alston attended Milford Township High School in Darrtown, and received the nickname "Smokey" as a high school pitcher, owing to the speed of his fastball. He graduated from high school in 1929 and married longtime girlfriend Lela Vaughn Alexander the next year. In 1935, Alston graduated with a degree in industrial arts and physical education from Miami University in Oxford, Ohio.

Alston played minor league baseball as an infielder for the Greenwood Chiefs and Huntington Red Birds in 1935 and 1936, respectively. For the 1936 Huntington team, he hit 35 home runs in 120 games. Alston's only major league game was with the St. Louis Cardinals on September 27, 1936, substituting for Johnny Mize at first base. He later described his major league playing career to a reporter by saying, "Well, I came up to bat for the Cards back in '36, and Lon Warneke struck me out. That's it." He also committed one error in two fielding chances at first base. Alston returned to the minor leagues after his brief MLB appearance. He split the 1937 season between the Houston Buffaloes and Rochester Red Wings, hitting for a combined .229 batting average. Alston played for the Portsmouth Red Birds in 1938, finishing the season with a .311 average and 28 home runs as Portsmouth won its only Middle Atlantic League championship. He returned to Portsmouth in 1940, hit 28 home runs and was a player-manager for part of the season. He was a player-manager for the next two seasons with the Springfield Cardinals and even appeared in seven games as a pitcher in 1942. He returned to Rochester as a first baseman and third baseman in 1943. He moved to the Trenton Packers, where he was a player-manager in 1944 and 1945. Alston had been offered the job in Trenton, a minor league farm club of the Brooklyn Dodgers, by Branch Rickey, the executive who had signed him as a player with St. Louis. After his two seasons with Trenton, Alston served as a player-manager for the first integrated U.S. baseball team based in the twentieth century, the Nashua Dodgers of the Class-B New England League. Alston managed black Dodgers prospects Don Newcombe and Roy Campanella, leading Nashua to a New England League title in 1946. Alston later said that he did not give much consideration to racial issues and that he had simply thought about how much they would benefit the team. Alston led the Pueblo Dodgers to the Western League title the next season. He appeared as a player in two games, which were his final professional playing appearances. For his 13-season minor league playing career, Alston hit .295 with 176 home runs. However, he hit only .239 in 535 at bats in Class AA, which was the highest minor league classification through 1945.

Why was that his only major league game?

Answer with quotes:

Background: Michael Kevin Taylor (born 17 January 1949) is an English musician, best known as a former member of John Mayall's Bluesbreakers (1966-69) and the Rolling Stones (1969-74). He has appeared on some of the Stones' classic albums including Let It Bleed, Sticky Fingers and Exile on Main St..
Context: After Brian Jones was removed from The Rolling Stones in June 1969, John Mayall recommended Taylor to Mick Jagger. Taylor believed he was being called in to be a session musician at his first studio session with the Rolling Stones. An impressed Jagger and Keith Richards invited Taylor back the following day to continue rehearsing and recording with the band. He overdubbed guitar on "Country Honk" and "Live With Me" for the album Let It Bleed, and on the single "Honky Tonk Women" released in the UK on 4 July 1969. Taylor's onstage debut as a Rolling Stone, at the age of 20, was the free concert in Hyde Park, London on 5 July 1969. An estimated quarter of a million people attended for a show that turned into a tribute to Brian Jones, who had died two days before the concert. The Rolling Stones' 1971 release Sticky Fingers included "Sway" and "Moonlight Mile" which Taylor and Jagger had completed in Richards' absence. At the time Jagger stated: "We made [tracks] with just Mick Taylor, which are very good and everyone loves, where Keith wasn't there for whatever reasons ... It's me and [Mick Taylor] playing off each other - another feeling completely, because he's following my vocal lines and then extemporizing on them during the solos." However, Taylor was only credited as co-author of one track, "Ventilator Blues", from the album Exile on Main St. (1972). After the 1973 European tour, Richards's drug problems had worsened and began affecting the ability of the band to function as a whole. Between recording sessions, the band members were living in various countries and during this period Taylor appeared on Herbie Mann's London Underground (1974) and also appeared on Mann's album Reggae (1974).

Question:
The Houston Livestock Show and Rodeo, also called RodeoHouston or abbreviated HLSR, is the largest livestock exhibitions and rodeo in the world. It also includes one of the richest regular-season rodeo events. It has been held at NRG Stadium in Houston, Texas, since 2003. It was previously held in the Astrodome.
Since 1952, traditional trail rides have been a part of the Houston Livestock Show and Rodeo. As of 2017, there were 13 official trail rides, totaling over 3,000 riders. The trail rides range in size from a dozen to over one thousand people who ride on horseback or in horse-drawn wagons from various areas of the state to Houston. They make their way at about 3 miles (4.8 km) per hour, covering up to 17 miles (27 km) each day. Many of the routes take place in part along major highways and busy city streets, making safety a major concern. The trail rides last from a few days to three weeks, depending on the distance they cover. Some of the participants are able to join only on weekends or at the end of the trip. The days start very early, and often end with live music or a small celebration. Many riders choose to camp in recreational vehicles rather than in the open. Each morning, they drive their vehicles and horse trailers to the next camping spot, then have a bus or convoy take them back so they can retrace their path on horseback. Participants can bring their own provisions, or, in some cases, purchase meals at a chuck wagon that is also following the trail. The rides converge at Memorial Park in Houston on Go Texan Day, the Friday before the livestock show and rodeo begins. The city closes some roads downtown to allow the riders to reach their destination safely. The resulting traffic interruption cause annual complaints from those who work downtown. The following day, all of the trail riders participate in the parade.
